Hi Julien,
Attached is a cleaned and prepared for import by the PIN.EXE from my library of Brother PPDs (I prepared them while I was deciding which printers to get).
Thank you ! Let me give that a try .
I did the following .
1) ran cleanppd.cmd on your PPD
2) copied the files from c:\sys\install\prndrv\pmdd_6 to c:\bro
{0}[c:\bro] dir
Volume in drive C is ARCAOS Serial number is A627:05B8

I tried different combinations of arguments, but always got the same issue. I had PSPRINT.DRV loaded from an existing printer object, but that shouldn't have been a problem since it was another copy in c:\bro . Anyway, I deleted all the printer objects referencing this driver, and still get this permission issue. Maybe one process still has it loaded somehow. But still, this shouldn't be an issue with the copied file.
